# Introduction to Equations

## About this tool

This is a simple activity tool that tells the basic things about the equation. So learn it and then practice yourself. Once done, try More on Equations.

Don’t forget to learn from more equation activities.

An equation is a mathematical statement that uses an equal sign to show that two expressions are equivalent. An equation typically includes one or more variables, which are letters or symbols that represent unknown values. The goal in solving an equation is to find the value or values of the variable that make the equation true. Equations can be used to solve a wide range of problems, from simple arithmetic to complex mathematical models used in physics, engineering, and other fields.

In math, equations can be written in a variety of forms, such as linear, quadratic, exponential, and logarithmic equations, among others. Each type of equation has its own unique characteristics and methods for solving. Linear equations, for example, involve variables that are raised to the first power and can be solved using basic algebraic techniques, such as isolating the variable on one side of the equation. Quadratic equations, on the other hand, involve variables raised to the second power and can be solved using factoring or the quadratic formula. Exponential and logarithmic equations involve variables in the exponent or logarithm and can be solved using logarithmic rules and other specialized techniques.
